PURPOSE:To improve capacity for imspecting bottles by sensing bottles for inspection by a rotary polyhedral mirror and detecting the reflected light through a fixed slit. CONSTITUTION:By means of an inspection apparatus composed of a rotary polyhedral mirror 6 for sensing inspected bottles 2, an objective lens 7 for detecting the reflection light from the mirror 6, a fixed slit 20 and a photoelectric conversion element 10, inspection output and the output from a detector for a bottle porition, is conducted signal processing and whether bottles 2 are good or not is decided 11. |
